Start at the blue golem, get help from both side and middle lane to kill the golm fast. Don't worry if they steal some XP as killing if faster and using less health potions will help you later on. Gain level two from the wolves and quickly move to wraiths. Take the red buff as you pass by to bottom lane to get the extra experience as smite should be off cooldown by now. With just one more sweep of the jungle you should have gotten to level 4 and taken Bandage toss. Look to see who has thier laned pushed more and dive twords that area, rinse and repeat. late game if the other team does not have a jungler, or their jungler is out in lane, Amumu can use bandage toss to scout the opposing jungle very fast, this can lead to an easy steal of the other teams Blue and red buff. If there is no support on your team, it might be wise to pick up a heart of gold so you can afford some wards for your team
